The fixed position function of very much now mobile phone instead " positional information " , include China for, millet. Actually, present major mobile phone all was used " locate jointly " means, used navigation system of 4 kinds of satellites at the same time, the fixed position function that has some of mobile phone so " correct oneself " , following plan institute are shown.
The buy inside the brave dragon processor that uses as a result of the major mobile phone that install eminent and kylin processor north is fought, chip of navigation of GPS, GLONASS, GALIEO, used the means that locates jointly, the user cannot choose to use independently north is fought or GPS, this is decided by mobile phone hardware, so how is the mobile phone examined system of which kinds of location to use? Can download [AdroiTS GPS Test Pro] mobile phone APP is examined.
Open a mobile phone " positional information " , outdoors environment opens afore-mentioned software, choose the 2nd " search satellite " , the usable navigation satellite that can see the mobile phone is searched, the north that what have label of small red flag among them is our country fights a satellite, be in certain zone, the signal that north fights a satellite is close friends at GPS satellite, following plan institute are shown.
In November 2017, our country and United States were signed " north is fought state jointly with look of GPS signal look and alternant operation " , realized the alternant operation of look of radio frequency look and civil signal, promoted navigation the precision of fixed position. Before, china and Russia had signed north to fight navigation system and Geluonasi the mutual and compatible each other of navigation system handles a deal.
The north of our country fights system of 3 navigation satellite, had enclothed " one belt all the way " country, provide accurate navigation and time service service. Our country predicts to launched 35 north to fight 3 navigation satellite 2020, realize global group net, when arriving in the whole world any positions can realize north to fight fixed position.
Anyhow, major now mobile phone is not onefold use GPS, support associated fixed position however, according to satellitic signal intensity, select appropriate navigation system, this is decided by mobile phone hardware. Accordingly, the instead of fixed position function of a lot of mobile phones " positional information " . Here reminds, malic mobile phone is done not have inside buy north fights chip, do not support north to fight navigation system, the mobile phone installing eminent of great majority supports north to fight navigation.
